Default Choke Constrictions

From your experience how much choke constriction would you expect to have in a 16 Ga barrel for :

Skeet ______
Imp Cyl ______
Mod _______
Imp Mod _______

The charts I have looked at online seem to be all over the place.

Thanks

The most accurate way to determine chokes is on a pattern board.

The answers should be fun. I doubt if 1 in a 100 shooters ever do a real pellet count.
Here are mine in order of requested:
.003"
.008"
'016"
.022"

I agree with you Dean 100%... but when looking to buy a gun the actual choke constrictions is all I have to go by unless there's a letter available. Being able to pattern it would be after it becomes mine.

The gun I'm referring to measures .006 & .017

Also keep in mind that patterns can, and will, be affected by the shell/loading used in it. With the same constrictions, varying the load can vary the percentages of the patterns considerably.

I do understand what Karl is trying to determine. Here's Hallowell's ideas on it. By giving a range for each, Hallowell is allowing for variances in choke profile and loadings used. Very smart, IMO.

I agree with Bob's figures, which are very close to Hallowell's figures. The gun you are considering is a classic improved cylinder and modified..

Those are most certainly what I would consider to be Skeet chokes on a 16 gauge.

IC/Mod, according to Hallowell. But his 12 gauge Mod range includes what I would consider a Light Mod and his Imp. Mod range includes what I would consider a Light Full.
